2 Claims. (Cl. 302-60) This invention appertains to ensilage-` blowers and' more particularly to a novelf attachment for a silo iillingpmachine.`

This usually results in the piling up of the ensilage distribution and un- Y However, by utilizing my is distributed evenly in the silo, thereby eliminating the above mentioned disadvantages.

My attachment A includes broadly a deflector hood I6 which is rockably mounted to the ex-V haust end I4 of the ensilage elbow I3. Extending from a crank lever I1, which is rigidly splined to the deector hood I6 for movement therewith, is a cable I8. The other end of the cable I8 is attached to a rotatably mounted crank arm 20 by means of a shorter crank arm 22. The crank armV 23 of an electric motor that any type of -motor may the crank arm 20, in of my invention I provide a motor of the backgear type. The motor 24 may be bolted to a bracket 24 which may be welded or otherwise secured to the blower B or any one ofY the The back gear type of rotates in a slow 24. While it is obvious be utilized to rotate motor is preferred because it and extremely steady manner. The, crank arm 20, as illustrated particularly in Figure 8, is provided with a series of apertures 25. Pivotally secured in one of the apertures 25, by means of a removable nut and bolt 23, is the shorter crank arm 22.v The upper end of the shorter crank arm 22 has formed thereon a right angularly extending portion 21 to which the end of the cable i3 isV adjustably fastened.

This adjustment of the cable I8 is due to the fact that the cable is fastened to the eye of a bolt 28,'"which in turn extends through a hole formed in the right angulariy extending portion 21 of the crank arm 22l Vinterposed between the top surface of the portion 21 and the eye of the bolt 28 under side of the portion'21 is a nut 33. ltcan be seen, therefore, that by tightening the nut 30, the bolt 23 will be pulled downwardly against the tension ofthe spring 29 and any slack in I8 will'be eliminated.

' I8 extends from the arm 22 over a pulley 3|, which may be tionl I2 or the ensilage elbow I3 by means of a bracket 32. The upper fastened, as stated above, to the crank lever I.

It should be apparent from the description thus far that when the back-gear motor is started, causing the rotation of the crank arms 23 and 22, that the -deiiector hood will be reciprocated from thefull line position toV thedotted line position as clearly shown fin Figure l of the drawings.

' rTherefore, ensilage issuing from the exhaust end I4 of the ensilage elbow I3 will be deflected and guided by the reciprocation of the arcuate shaped derlector hood and deposited in the silo S as indicated by the arrows. The ensilage, indicated the letter E (Fig. l), is deposited in an even straight line from the front to the rear of the silo as indicated by the letter L. However, it is also of the utmost importance that the ensilage E be distributed evenly to the right and left in the silo S, as indicated by Figure 2 of the drawing. This is accomplished by providing the end of the curved I6 with a number of longitudinally extending guide vanes 33, 33 and a conically shaped depending guide finger 34.

The disposition of the guide nger 34 and guide vanes 33, 33 is clearly illustrated in either Figure 4 or 6 of the drawings, and noted that the depending guide finger 34 is attached centrally of the discharge end of the deflector hood I6 between the diverging ends of the two center guide vanes 3 The portion of the guide finger 34 which Ycontacts the flowing ensilage is conically shaped so that (Figure 6) the ensilage may be deflected outwardly and downwardly as indicated by the arrows. It can now be seen that not only is posited evenly in a straight line from the front to the rear of the silo S, but, by means of the guide vanes 33, the guide finger 34, a part of the ensilage is guided wardly to be deposited evenly left sides of the silo.

In utilizing the deflector hood I6 with certain types of' ensilage, or with silos of larger diameters, it may beY desirable to tive and lengthened flowing from the discharge end, so when neces- I provide extensions 35 which may be the Vguide vanes 33, 33 by nuts and to the right and bolts 36 Yextending through perforationsV 31.

in the guide vanes 33, 3 In order to acilitatethe easy my deiieotor hood I3Yto thepdischarge end a standard ensilage elbow I3,*Ihave novel attachment means which is rigidly secured to the discharge end I4 by'means brackets 38. The brackets 38 are firmly attached to the sides 39 ofthe discharge end I4 by welding or any other suitable method. Bolted to the brackets 38 are a pair of identically formed bearing members 40. The bearing members 40 include Va slot 4I, an upwardly extending rear leg 42, and a shorter front leg 43. VThe front leg 43 has its forward and upper endrourved slightly as indicated at 44 and illustrated in partieular in Figures 3 and 4.0i the drawings. ookably received in the slots 4I is a to one end of which is rigidly splined the crank lever I'I.- The pivot bar 45 is provided with a longitudinal undercut portion intermediate its ends; to which is'firmly' bolted by means of bolts 43, therear end of the defiector hood pivot bar 45 is held inits supporting bearings by means of cotter upright legs 42, 43 `and over the top portion of the pivot bar 45. When it is desired to attach the defiector hood to the end I4 ofthe ensilage pivot bar 45 is placed forwardly of the supporting bearings 40 ward direction. VBy means of the curved portion 44 of the front leg 43, the ends of the are conducted upwardly and into the slot 4I. Thus it can be seen that the deflector hood may be'easily attached by any ordinary layman without the employment of skilled help'. Y
